Application filed January 23, 1915. Serial No. 3,855.

To all whoa. t it may concern:

Be it known thatl, ALBERT H. Dn Von,

a citizen of the United States, residing at VVestfield, in the county ofUnion and State 5 of New Jersey, have invented certain new and usefulImprovements in Seams for sewed Articles, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention has for its object to provide a seam which is adapted foreither uniting or ornamcnting fabrics, or both. In its preferred form,the seam is used to connect the laterally spaced margins of two piecesof fabric which may be joined by an underlying strip of fabric, or maybe held together solely by the scam. I

In the production of the preferredform of seam, four lines ofstraightaway stitches may be simultaneously formed with the outer ormore remote lines passing through the margins of the first-namedfabrics. Intermediate the outer and adjacent lines of stitching aredisposed covering or cross threads formed alternately at opposite sideswith lateral twisted loops secured in position respectively by saidouter and adjacent lines of stitches. Between each two of said lines ofstitches intermediate the outer lines is disposed another coveringthread similarly formed with alternately and oppositely extendingtwisted loops secured in positis'n by said two lines of stitches witheach of such twisted loops disposed between the corresponding loops ofadjacent covering threads secured in position by the same lines ofstitches. The sea-m, may however be composed of three or any largernumber of laterally spaced straightaway seams connected 40 together byone less than an equal number of covering or cross threads, and thesethreads may be in colors in contrast with each other and the fabrics towhich they are connected, which may also be in contrasting colors, andparticularly the underlying or backing strip when. employed inconjunction with the mar- The straightginally connected fabrics. awaylines of stitches may be of the lockstitch type, but are preferablycomposed of single or double-chain stitches affording elasticitylengthwise of the seam to corre-' spond with the lateral elasticityafforded by the described arran ement of the loops of the cross-threads.hen constructed as described, the seam may be made independent thefastening threads 6.

hereinafter appear.

The invention will be understood by reference to the accompanyingdrawings, in which- Figure 1 is a face view of two fabrics marginallyconnected by a scam embodying the present improvement, and showing oneend rolled up to expose the under face; and Fig. 2 is a similar view ofthe scam as applied to spaced marginal portions of two fabrics with anunderlying backing strip.

Referring to Fig. 1, the fabrics 1 and 2 are shown with spaced marginalportions turned under to form hems 3 and 4, respectively. Applied to themarginal portions of these pieces of fabric are the two outer or moreremote lines of stitches 5 of a series of four rows, with loops 5 eachpassed through its respective fabric and embracing the succeedingthread-loop to form the well known single-chain stitch. Lines 6 ofsimilar chainstitches are shown disposed intermediate the outer linesdand the margins of the two fabrics with concatenated loops 6 similar tothose of the other scams.

Each outer line of straightaway stitching 5 and the adjacentintermediate line 6 are connected together by means of an embroidcry orcross thread 7 which is formed with rows of lateral alternating-andoppositely extending twisted loops 7 and 7 each loop 7 being entered bya loop 5 of its respective fastening seam by which it is secured inposition upon themargin'of the respective fabric, while each loop 7" isentered and secured in position by loop 6 of one of the intermediatelines of straightaway stitching.

The intermediate lines 6 of stitching are similarly connected by anembroidery or cross 'thread 8 formed with oppositely extending lateraltwisted loops8, which are interposed between the loops 7 of the adjacent cross threads and entered by loops of The cross-thread loops arethusformcd in rows corresponding with the several lines of fasteningstitches, the loops of the adjacent cross threads secured in position bythe intermediate lines of straightaway stitches being alternated inarrangement and therefore more closely grouped together than the loopsfastened by v the outer lines of stitches so as to produce theappearance of greater density in the middle portion. of the compositeseam thus formed than in the edge portions thereof, thereby producing acontrast which contributes to the ornamental appearance of the seam.

The seam, as disclosed in Fig. '2, is like that of Fig. 1, excepting inthe addition of the backing strip 9 having its marginal portions 10turned over and interlocked with the hems 8 and l of the marginallyspaced fabrics 1 and 2. In this form of the improvement, theintermediate lines of fastening stitches 6, instead of being formed inthe air, are applied to the backing strip, and the cross-thread loopsthrough which they pass are securely attached to the face of the backingstrip.

As represented in the drawing, the outermost twisted loops of embroideryor cross thread are bound upon the faces of the fabrics 1 and 2 by theirrespective fastening seams, but it is evident that by the employment ofzigzag or overedge seams in lieu of the straightaway stitch scams 5,these covcling-thread loops may be secured to the edges of the fabricswithout overlapping. It is therefore not essential that the laterallyextending loops of the covering threads be secured in position bystraightaway stitch seams, and it is evident that the character of suchfastening seams is not material to the present invention.

Various modifications of the structure shown and described may obviouslybe made within the scope of the appended claims.

The invention is not therefore to be considof stitches of a commonintermediate row.' .2. A seam for sewed artlcles comprising incombination, fabric, a plurality of at least three independent rows ofstitches'disposed therein, and cross-threads looped back and forthbetween adjacent rows of stitches,

there being a separate cross-thread connecting each two adjacent rows,respectively, adj ac'ent loops of adjacent cross-threads being enteredand secured in alternate arrangement by lnpps of stitches of a commonintermediate row.

A seam for sewed articles comprising adjacent rows of stitches, therebeing a sep arate 'cross-thread connecting each two adacent rows,respectively, ad acent loops of adjacent cross-threads being entered andsecured in alternate arrangement by loops of stitches of a commonintermediate row.

4. A seam for sewed articles comprising in combination, two spaced edgeportions of fabric, an intermediate strip of fabric extending betweensaid edge portions of fabric, a plurality of at least three independentlines of stitches of which the extreme oiiter rows are disposedrespectively in the edge portions of fabric and serve to secure thestrip thereto, and cross threads looped back and forth between adjacentrows of stitches, there being a separate cross-thread connecting eachtwo adjacent rows, respectively, adj acent loops of adjacentcross-threads being entered and secured in alternate arrang ment byloops of stitches of a common intermediate row.

5. A sewed thread structure comprising a plurality of at least threeindependent lines of stitches, and a smaller number of cross threadseach formed with rows of lateral alternating and oppositely extendingtwisted loops of which those at the adjacent sides are entered andsecured in position in alternate arrangement by loops of stitches of acommon intermediate line and those at the opposite sides by loops ofstitches of other lines.

6. In a scam, the combination with two tion respectively by loops ofstitches of adjacent lines intermediate said outer lines and alternatingwith the twisted loops of the adjacent cross threads secured by the samelines of stitching and in alternate arrangement with such cross-threaiiloops.

7. In a seam, the combination with two fabrics having their adjacentmargins spaced apart, and a strip of fabric overlaid by and extendingbetween said n'1ar, ins of the first-named fabrics, of a plurality ,ofat least four independent lines of stitches it o twisted loops enteredand secured in posiof which loops of the stitches of the extreme outerlines are passed respectively through the'margi'ns of said fabrics andthe underlying strip and loops of stitches of the intermediate lines arepassed through said strip of-fabric between the margins of the first-'name'd fabrics, cross threads each formed with rows of lateralalternating and oppositely extending twisted loops entered and securedin position respectively by loops of stitches of one of said outer linesand loops of stitches of the adjacent line, and another cross threadsimilarly formed with oppositelyextending lateral twisted loops enteredand secured in position respectively by loops of stitches of adjacentlines inter mediate said outer lines and alternating with the twistedloops of the adjacent cross. threads secured by the same lines ofstitching and in alternate arrangement with such cross-thread loops.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
